Using the following equation, what does L equal?

A
B
C or
D?

Answer:

A. Approximately 85 m

Step-by-step explanation:

edge

The required distance between the origination point and the target point is 85 m.

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.

Here,
The distance between the origination point and mirror 1 is 120 m and between mirror 1 and mirror 2 = 90 m

From geometry, the measure of the angle Opposite the distance between the origination point and the target is given as,
= 20 + 25 = 45°

Let,

a = x

b = 90 m

c = 120 m

A = 45°

Following the cosine rule,

a² = b² + c² -2bccosA

a² = 90² + 120² - 2×90×120×cos45
a = √7226.5
a = 85.008

a ≈ 85

Thus, the required distance between the origination point and the target point is 85 m.

Answer:

9 is the answer

Step-by-step explanation:

if it was less then ten and not a multiple of 2 then i will ether be 1 3 5 7 9  but the composite numbers are 4 6 8 9 so since it is not a factor of 2 it has to be 9. so 9 is the answer

The number which is less than 10,  not a multiple of 2, and is a composite number, is 9.

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

Given:

I am less than 10 l am not a multiple of 2 l am a composite number,

The numbers which are less than ten are,

9, 8, 7, 6, 5, 4, 3, 2, 1, 0

The numbers which are not the multiple of 2 are shown below,

9, 7, 5, 3, 1, 0

The numbers which are composite are shown below,

9 = 3 × 3

Thus, The number is 9.

Answer:

4.75

Step-by-step explanation:

original price (100%) → $19

discounted price ((100-75)%) = (25%) → 25% x $19 = $4.75

Answer:

Step-by-step explanation:

Here's what we have to do:

1. 19 x 0.75

= 14.25

2. 19 - 14.25

= 4.75

3. 4.75 + 14.25

= $19

The Discount is $4.75, and the sale price is $19.00.

Answer:

1)110m^2

2)1.75m

3)96.25m^2

Step-by-step explanation:

Rate of painting= The cost to paint it /

inner curved surface area of the vessel

20m^2=(Rs 2200 /inner curved surface area of the vessel)

If we make inner curved surface area of the vessel subject of the formula,

inner curved surface area of the vessel= =(Rs 2200/20)

= 110m^2

2)cost surface area of a cylinder can be calculated using expression below

(2πrh,) then the values was calculated in question 1 as 110m^2

Then from (2πrh=110) we can make "r" subject of the formula

r= 110/(2πh). h=10m deep

r=110/(2×3.14×10)

r= 1.75m

3)(iii)capacity of the vessel (in litres

The capacity of the vessel can be regarded as the volume which equals to πr^2h

From question 2 r=1.75m, and h=10m

Then

πr^2h= 3.142×(1.75)^2 ×10

=96.25m^2

Hence the capacity is 96.25m^2

Answer:

A

Step-by-step explanation:

because 1/2 = 4/8

and 5/8 is greater than 4/8  

The number line is the representation of numbers in real order.

5/8 = 0.625

1/2 = 0.50

5/8 is greater than 1/2.

Option A is the correct answer.

It is the representation of numbers in real order.

The difference between the consecutive numbers in a number line is always positive.

Example: Number line from -4 to 4.

-4__-3__-2__1__0__1__2__3__4

We have,

5/8 > 1/2

5/8 = 1/2

5/8 < 1/2

5/8 = 0.625

1/2 = 0.50

We see that,

0.625 > 0.50

So,

5/8 must be greater than 1/2

i.e

5/8 > 1/2

We can also find the relation between 5/8 and 1/2 in this way.

5/8 = 1/2

Cross multiply.

5 x 2 = 8

10 = 8

10 is greater than 8

So,

5/8 is greater than 1/2

5/8 > 1/2

Thus,

5/8 = 0.625

1/2 = 0.50

5/8 is greater than 1/2.

Option A is the correct answer.

6x^2 + 12x + 3x + 6

6x^2 + 15x + 6

Answer:

6x² + 15x + 6

Step-by-step explanation:

Use FOIL:

Multiply the first terms:

(2x)(3x) = 6x²

Multiply 2x and 6:

(2x)(6) = 12x

Multiply 1 and 3x:

(1)(3x) = 3x

Multiply 1 and 6:

(1)(6) = 6

Then, add these all together:

6x² + 12x + 3x + 6

Add like terms:

6x² + 15x + 6 is the simplified expression

First of all, the variables have to be selected to represent the quantities.

Let m be the number of male friends and let f be the number of female friends.

Then according to first statement "John has 30 friends"

[tex]m+f = 30\ \ \ \ Eqn\ 1[/tex]

And according to second statement "amount of male friends is 4 more than the number of female friends."

The probability of purchasing mineral rights

Form the first mountain [tex]p_1=0.55\\[/tex]

From the second mountain [tex]p_2=0.4[/tex]

As the decision is made independently

So, P([tex]p_1[/tex]∩ not[tex]p_2[/tex]) [tex]=0.55 \times 0.6\\[/tex]

P([tex]p_1[/tex]∩ not[tex]p_2[/tex]) [tex]= 0.33\\[/tex]
